To all uihom it may con/cern,.-

`Be it known that LSAMUEL J. REEvEs, of

the city and county of Philadelphia, and State oi" Pennsylvania, have-invented certain new and useful Improvements in the Construction of Wrought-Iron Shaftsor Columns, Braces, or

` Chords for Houses, Piers, Bridges,l Ste.; and I do hereby declare that the followingis a full,

clear, and exact description of the same, reference being had tothe accompanying drawings, making 1a partof this specification, in which- 4 Figure 1 represents a shaft or ycolumn par- Fig. 24 represents a transverse section through-the samen Fig. 3 represents a portion of a transverse section on an Fig. 4 represents a transverse t section of a` column ina modified form.

enlargedscale.

I have invented a novel Inode of making a shaft or column of. wrought-iron, which com- 'bines the advantage `oi' being useful as a vertitcalfpost, horizontal brace, or compressionchord in the construction of, houses, piers,

bridges, and other structures, and at the same time admitting (Where several of them are to be used together to form a truss, as in a bridge, Ipi er, or observatory) of a convenient and cheap arrangement for fasteningthe ties and braces.

- I use threeor more wrought-iron bars, similar to those marked@` a a a in the annexed drawings, to which reference is hereby made, n of such shapes and dimensions, that when arranged together inthe directionl of their length, and fastened by rivets or bolts c through their flanges b, they shall form a hollow shaft `or column. When itis intended to usetwo or more of these shafts combination with ties or braces, instead of bringing the iianges in contact with each other, I interpose Washers oi' any desired thickness for the purpose of admitting the ends of the ties and braces between thetlanges, and of riveting or bolting them together, thus uniting the Whole in the most suitable manner and at small expense. The pieces a a a a are so designed that they can be rolled, by raising ordepressing the rollers, to any desired thickness without increasing the external diameter of the column proposed to be'made, so that a series of columns resting one upon another may be made of diierentinteriordiameters and weights proportioned to the loads to be sustained, but having the externalappearance of one uniform shaft.

The stiffness and strength of columns made as braces or eompressionchords, inthe coni struction of buildings, bridges, piers, or other structures. .t l
